Hello y'all:

Thank you for the feedback.  I will look into the FFMPEG source and  
see what we can do.



Thank you again

Take care

Garrett

Hi Garret, Hi David,

I ran into the same issue a few months ago.  The solution I ended  
up with was frame grabbing during each cycle.  Afterwards, I strung  
the frames back together into MOV/AVI/MPG movies with FFMPEG.  It  
works, but it will probably drop your frame rate significantly.  I  
was able to slow down the data stream feeding my OSG application to  
ensure that I grabbed enough frames to generate a decent quality  
video.




I believe that FFMPEG is open source, so a movie maker plugin could  
be built on top of it.  Just a thought.

Hi Garrett

  A xine/Quicktime plugin is provide to read movie in OSG scene
 Take a look to osgmovie examples.

 But don't know any plugin to make a movie from an OSG Scene

Hello All:

I have been perusing the source and examples and I was wondering if
there was a way to output movies in an OSG Scene.  I know there are
pbuffers and you can probably latch on to pbuffer generation after
each framing and then couple to a movie generation library but I see
that the osgDB has a nice plugin architecture for reading and writing
and was wondering with the Movie based plugins if there was a way to
feed a plugin (if one exists for movie writing) to output frames at
given rate.  So basically init the plugin with some setup parameters
and then start writing.  Has anyone ever researched this through a
raw OSG implementation and not coupled to like a GUI or anything like
that?

Thank you all in advance for any help and time.

Take care

Garrett
